Abstract

This brief describes a low-power current-mode voltage reference based on subthreshold transistors. A novel circuit configuration together with a high-order temperature compensation scheme allow this voltage reference to operate with a supply voltage down to 0.4 V over a large temperature range (from -40 degrees C to 130 degrees C). The circuit, which is fabricated with a standard 0.18-mu m CMOS technology, provides an output voltage of 212 mV, while consuming 192 nW. The measured average temperature coefficient is 84.5 ppm/degrees C.
